Description 332-334
Totally 37
strains from the three biota were isolated with predominance of Bacillus spp.
followed by Pseudomonas spp. Spirillium spp., and Vibrio spp.
Based on the fatty acid profile, a few of the strains were identified as Pseudomonas
mesophilico, Pseudomonas caryophylli and Bacillus cereus. Of the
three biota studied, the coral reef harbours higher percentage of magnetotactic
bacteria followed by the mangroves and estuaries. The strains were further
studied for growth, salinity optimum, magnetotaxis and survival. The bacterial
growth was observed as a ring form ion between 7 and 14 days

of inoculation. The distance
to the ring from the top surface of culture medium ranged from 0.5 to 4.6 cm.
The ring was prominent in a salinity of 20 ppt. Regarding magnetotaxis, a 3 h
exposure to the external magnetic field was required for 100% aggregation of
bacterial cells. The magnetobacleria isolated from coral reef were able to
survive for 5 to 6 months whereas those from mangroves and estuaries survived
for 4 and 2 months respectively.
